SYSTEM FOR AERATING ICE GANS Filed Feb. 15.A 1927` 2 sheets-sheet 2 Patented Dec. 17, 1929 PATENT oFFc JOSEPH A. MAaTocELLo, or PHILADELPHIA, PENNSYLVANIA SYSTEM FOR AERATING- ICE CANS Application filed February 15, 1927. Serial No. 168,267.

My invention relates to aerating connec-V tions for ice cans and to so-called can baskets comprising units of a number of cans each of which is used in the manufacture of ice.

One purpose of my invention is to provide bottom insertion of air within each can and to connect up the opening removably with an outside lateral carried by the basket.

A further purpose is to provide a lateral and aerating pipe connections therefrom with an intermediate valve having a removable valve member containing an air restriction and capable of being substituted by another valve to give a different air restriction.

A further purpose is to provide a trap for dirt or other foreign material in the air line of an ice can air supply and in the form of a removable restricted valve opening.

A further purpose is to provide a novel bottom air inlet.

A further purpose is to provide an ice can basket with a lateral extending along the ends of the cans and with connections extending down the ends of the cans and along the bottoms thereof to a bottom air inlet.

Further purposes will appear in the specification and in the claims.

I prefer to show one form only of my invention with slight modifications, selecting a form which is practical, efficient, reliable and inexpensive and which at the same time well illustrates the principles of my invern. tion.

Figure 1 is a perspective and associated parts.

Figure 2 is a. fragmentary, vertical section corresponding to line 2-2 of Figure 1 but with a can of slightly vdifferent shape.

Figure 3 is a fragmentary section through kof the can, basket '40 the bottom of the can at an air inlet.

Figure 4 is a side elevation and vertical longitudinal sectionl at and through the oint between the lateral and the header.

Figure 5 is a section showing a slight mod- 45 ification as compared with Figure2.

YFigure 6 is a fragmentary enlarged section of a portion of Figure 5. It corresponds with line 6-6 of Figure 7.

Figure 7 is a side elevation partly in sec- 59 tion upon the line 7-7 of Figure 6.

Figure 8 is a fragmentary vertical sec-` tion showing a further modification.V

Figure 9 is a fragmentary perspective partly broken away to show the interior, of an additional form of my invention.

In the drawings similar numerals indicate like parts.

In the can basket 15 shown the cans 16` have the usual upper rims 17 forming outwardly extending end ledges which are supported from side frame members 18 and 19 2y strips 2() secured to the side frame memers.

The side frame members are united by end frame members 21 secured to the side frame members by any suitable means such as bolts 22. Stiffening transverse members 23 and 24, 25and 26 are shown united to the side fra-me members at 27. They perform the further function of .supporting lifting pins 28 to be engaged by the usual crane lifting hooks through which the baskets are handled. `Upward movement of the cans within ghe basket is prevented by removable plates Under the side of one of the frame mem-V bers is secured a lateral 30 which may extend about the end of the basket also as at 30" for more convenient placing of a fitting 3l. The upper end of fitting 31 supports a fixed valve plug 32. Y

Hose connections 33, 33 from a header 34 terminatein nozzles 35 fitting into openings 36 in the valve plugs. The openings are suited to receive thawing needles' and are sur-y rounded by guides 37 for these needles. The nozzles open spring-pressed valve closures 38 within the plugs. The spring-pressed valves are held to their duty by hollow plugs 39.

Each air inlet shown takes place through. the bottom of the can which is apertured at 40 so as to receive tubular boss 41. The boss extends above the bottom of the can and serves as a discharge nozzle. The boss is carried by plate 42 which directly or through a gasket kseals `against the bottom of the can and is united with the can as by rivets 43.

The air inlet opening 44 is in line with and connects with a socket opening 45 for pipe terminal 46. The pipe terminal is held and is 18 and the pipe 5O2'eXtends Idownwardly besealed by a stuffing boX gland 47 and packing 48.

F rom the lateral to the terminal pipe 46 I show three different but much similar connections. One extends downwardly at 50 along a groove 5l in the end of the can (Figures land @passing througlrthefend ofthe can below the levelY of the bottom ofthe can. In another form thepipe extendsdiagonahy as at 50 (Figure-,5)betweenjthegcans .and passes through the lower side edge of the can below the level of the bottonr ofdthecanas at 51.

In a third form shownin-'FigureS thef-lateral is placed inside the sideframe member tween a top can Arim and thecan into anddown alongthe groove l'in the 'side of the can fol Vlowing the groove attheb'ottomV and lpassing throughgthe bottom edge ofthe canas inthe construction shown inFigureQ.
